Significant Figures and Area Calculations

Aaliyah calculates the area of a garage using measurements of 5.23 M and 6.14 M. The video explains that the precision of the measurements dictates the precision of the result. Since both measurements have three significant figures, the area result should also have three significant figures, resulting in an area of 32.1. The video emphasizes that in multiplication, the result should have the same number of significant figures as the least precise measurement.

What are the measurements Aaliyah is using to calculate the area of the garage?

• 5.32 M and 6.14 M

• 5.23 M and 6.14 M

• 5.32 M and 6.41 M

• 5.23 M and 6.41 M

How many significant figures do the measurements 5.23 M and 6.14 M have?

• Two significant figures

• Three significant figures

• Four significant figures

• Five significant figures

Why should the area calculation result have three significant figures?

• Because it is a requirement for all area calculations

• Because it is easier to calculate

• Because both measurements have three significant figures

• Because it is a standard rule for all calculations

What is the calculated area of the garage with the correct precision?

• 32.100

• 32.11

• 32.10

• 32.1

In a multiplication problem, the result should have the same number of significant figures as which factor?

• The largest factor

• The first factor

• The least accurate factor

• The most accurate factor
